  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • FFMPEG conversion error from MKV to MP4 using libfdk_aac codec

    23 août 2014, par Charlie Brown

    The purpose of doing this is because my "Smart" samsung TV doesn’t play MKV files.

    This thread mentions that there is no need for video conversion, just changing the container might suffice. After reading multiple threads on how to change the container of MKV to MP4, I downloaded and compiled the FFMPEG with libfdk_aac support from here. I tried converting a sample MKV file using this command :

    ffmpeg -i "C:\VideoTest\Sample1.mkv" -c:v copy -c:a libfdk_aac -b:a 384k "C:\VideoTest\Sample2.mp4"

    but getting the following errors (copied from command prompt) :

    [hevc @ 0000000000308ae0] Could not find ref with POC 113

  • C# console app to process FFMPEG jpg stream output

    15 septembre 2014, par Gabriel Barzola

    I am looking some tip or idea in order to process an stream of jpg files created by a fFMPEG command.

    There is a way to split the outpuStream to capture each jpg file ?

    Here is the command
    ffmpeg -i rtsp ://somertsp:554 -an -f image2pipe -vf fps=fps=5 -

    I execute that command using a C# application.

    Here is a example code

    class Program

    private static BackgroundWorker worker;
    
    private static MemoryStream buffer = new MemoryStream();
    
    private static BinaryWriter bufferWriter = new BinaryWriter(buffer);
    

    
    static void Main(string[] args)
    
    {
    
        string file = @"C:\ffmpeg\bin\ffmpeg.exe";
    
        string arguments = @"-i rtsp://xxx:yyy@v5demo.wavestore.com:554/rtsp/00004 -an -f image2pipe -vf fps=fps=5 -qscale 0 -";
    

    
        var processStartInfo = new ProcessStartInfo(file, arguments);
    
        processStartInfo.CreateNoWindow = false;
    
        processStartInfo.RedirectStandardError = true;
    
        processStartInfo.RedirectStandardOutput = true;
    
        processStartInfo.UseShellExecute = false;
    

    
        worker = new BackgroundWorker();
    
        worker.DoWork += worker_DoWork;
    
        worker.WorkerReportsProgress = true;
    
        worker.ProgressChanged += worker_ProgressChanged;
    

    
        var process = new Process();
    
        process.StartInfo = processStartInfo;
    
        process.Start();
    

    
        worker.RunWorkerAsync(process);
    
        process.WaitForExit();
    

    
    }
    

    
    static void worker_ProgressChanged(object sender, ProgressChangedEventArgs e)
    
    {
    
        // save the image
    
    }
    

    
    static void worker_DoWork(object sender, DoWorkEventArgs e)
    
    {
    
        try
    
        {
    

    
            var internalWorker = sender as BackgroundWorker;
    
            Process p = e.Argument as Process;
    
            buffer = new MemoryStream();
    
            bufferWriter = new BinaryWriter(buffer);
    
            using (var reader = new BinaryReader(p.StandardOutput.BaseStream))
    
            {
    
                while (true)
    
                {
    
                   //get the jpg image
    
                }
    
            }
    

    
        }
    
        catch (Exception ex)
    
        {
    
          // Log the error, continue processing the live stream
    
        }
    
    }
